8. What is the name of the property of equality or congruence that justifies going from the 1st statement to the second statement?

9. What is the name of the property of equality or congruence that justifies going from the 1st statement to the second statement?

10. Proof: a convincing argument that uses deductive reasoning (shows why a conjecture is true) Two-Column Proof: lists each statement on the left and the justification or reason for each statement on the right. Each step must follow logically from the steps before it.
